Dame Marjorie Morris Scardino, DBE, FRSA (born 25 January 1947) is an American-born British business executive. She is the former CEO of Pearson PLC. Dame Marjorie became a trustee of Oxfam during her tenure at Pearson [1]. She has been criticized by Private Eye magazine because, while Oxfam campaigns against corporate tax avoidance as part of the IF Coalition [2], Pearson was "a prolific tax haven user...routing hundreds of millions of pounds through an elaborate series of Luxembourg companies (and a Luxembourg branch of a UK company) to avoid tax".[2] She became the first female Chief Executive of a FTSE 100 company when she was appointed CEO of Pearson[3] in 1997. She is also a non-executive director of Nokia[4] and former CEO of the Economist Group.[5] During her time at Pearson, she had tripled profits to a record £942m.[6] In December 2013, she joined the board of Twitter[7] as its first female director, after a controversy involving a lack of diversity on the Twitter board.[8]
